Description

Technical Field

[0001] The invention relates to the field of fire extinguishing devices, in particular to a portable fire extinguishing device for unmanned aerial vehicles. Background Art

[0002] In fire rescue, drones carrying fire-fighting equipment can quickly reach the fire scene, especially some areas that are difficult for personnel to reach, thereby improving rescue efficiency and protecting the safety of rescuers.

[0003] At present, drones carrying fire extinguishing balls are one of the common ways to extinguish fires. In actual operation, drones transport fire extinguishing balls to the top of the fire point, and then release the fire extinguishing balls, which burst above the fire source, allowing the fire extinguishing agent inside to quickly cover the fire source, thereby achieving the purpose of extinguishing the fire.

[0004] However, existing fire extinguishing balls mainly rely on timers to control the release timing of the fire extinguishing agent, and the setting time of the timer is fixed at the factory, and cannot be flexibly adjusted according to the complex conditions of different fires in actual rescue. This limitation causes the activation and fire extinguishing effect of the fire extinguishing ball to be subject to the flight altitude of the drone. In order for the fire extinguishing ball to have sufficient response time, the drone needs to fly at a higher altitude. When the drone flies at a lower altitude, the timer may be set too long, causing the fire extinguishing ball to release the fire extinguishing agent deep into the flame. At this time, the fire extinguishing agent breaks in the fire source, and the high temperature of the flame and the strong airflow may hinder the diffusion of the fire extinguishing agent, thereby affecting the fire extinguishing effect.

[0024] refer to Figure 1-4 A portable fire extinguishing device for unmanned aerial vehicle comprises a fixed shell 1, a sealing component 2, an installation component 3, a blasting component 4, and a control component 5. The fixed shell 1 is a main body for carrying a fire extinguishing substance. The fixed shell 1 is filled with a fire extinguishing substance. The fire extinguishing substance may be a dry powder or a water-based fire extinguishing agent. The fixed shell 1 may be made of a plastic material that is easily broken by impact. Thus, when the fire extinguishing device reaches above a fire source and needs to release the fire extinguishing substance, the fixed shell 1 can be rapidly broken under the action of the blasting component 4, thereby ensuring that the fire extinguishing substance is released quickly and in a timely manner. The sealing component 2 is arranged at the top of the fixed shell 1, which can realize the sealing of the fire extinguishing substance in the fixed shell 1, avoid leakage of the fire extinguishing substance, ensure the stability of the fire extinguishing device during transportation and storage, avoid performance degradation or failure caused by leakage of the fire extinguishing substance, and ensure that the fire extinguishing device is in a usable state at any time. The installation component 3 is arranged at the top of the sealing component 2 The entire fire extinguishing device can be connected to the drone through the installation component 3, ensuring that the device can be safely and stably mounted on the drone, ensuring the safety and reliability of the transportation process, and enabling the drone to smoothly deliver the fire extinguishing device to the fire scene. The blasting component 4 is arranged at the bottom of the sealing component 2 and extends into the fire extinguishing material. When the blasting component 4 is started, the impact force it generates can quickly break the fixed shell 1, and at the same time, fully spread the internal fire extinguishing material to evenly cover the fire source and enhance the fire extinguishing effect. The control component 5 is arranged in the sealing component 2 and is electrically connected to the blasting component 4. The control component 5 can realize precise control of the blasting component 4, accurately control the blasting timing of the blasting component 4, ensure that the fire extinguishing material is released at the right time, and avoid the fire extinguishing device from exploding after entering the fire source when the drone's flight altitude is insufficient, thereby effectively extinguishing the fire.

[0025] In some embodiments, the mounting assembly 3 includes a fixing plate 31, a mounting plate 32, a mounting hole 33, and a reinforcing plate 34. The fixing plate 31 is arranged on the top of the sealing assembly 2 and is detachably connected to the sealing assembly 2. Bolts or snaps can be used to facilitate the installation and removal of the mounting assembly 3 and the sealing assembly 2, facilitate the maintenance of the device, and improve the operating efficiency. The mounting plate 32 is arranged on the top of the fixing plate 31 and can be directly docked with the drone. The mounting hole 33 runs through the mounting plate 32. The mounting frame of the drone can be connected through the mounting hole 33 using hooks, latches, etc. The components are closely connected to the mounting plate 32, so as to realize the mounting of the fire extinguishing device, ensure that the fire extinguishing device can stably fly to the fire scene with the drone, and facilitate the separation of the fire extinguishing device from the drone. The two reinforcing plates 34 are symmetrically arranged on both sides of the mounting plate 32. The reinforcing plates 34 can enhance the overall strength of the mounting assembly 3, ensure that the mounting plate 32 can withstand the weight of the fire extinguishing device and various forces during the flight during the flight of the drone, and will not be deformed or broken due to excessive force, thereby ensuring the safety and reliability of the fire extinguishing device during transportation.

[0026] In some embodiments, the sealing component 2 includes a connecting ring 21, a sealing platform 22, and a placement groove 23. The connecting ring 21 and the fixed shell 1 can be detachably connected and can be threadedly connected, which is convenient for the installation and separation of the connecting ring 21 and the fixed shell 1, and realizes convenient filling and replacement, ensuring that the fire extinguishing device has effective fire extinguishing capability at any time. The sealing platform 22 is arranged on the top of the connecting ring 21, and the sealing platform 22 is provided with an installation component 3. The placement groove 23 is arranged on the top of the sealing platform 22, and the placement groove 23 is provided with a control component 5. The inner wall of the placement groove 23 can be made of rubber or silicone material with good insulation and shock absorption properties. On the one hand, it can prevent the control component 5 from being damaged due to external collision and friction. On the other hand, it can effectively shield external electromagnetic interference to ensure the stable operation of the control component 5.

[0027] In some embodiments, the fixed shell 1 includes a shell 11, a fixing ring 12, a filling cavity 13, and a plurality of grooves 14. The shell 11 can be spherical and can be made of high-strength engineering plastics with a certain degree of flexibility. It can ensure that the fixed shell 1 will not be easily damaged during daily transportation and storage, and can quickly break when impacted by the blasting component 4 to release the fire extinguishing substance. The fixing ring 12 is arranged on the top of the shell 11 and is connected to the connecting ring 21. It can be connected by threads, and the threaded connection between the fixing ring 12 and the connecting ring 21 can be filled with sealant to achieve sealing when the sealing component 2 is connected to the mounting component 3, avoid leakage of the fire extinguishing substance, and enhance the structural stability of the entire device, ensuring that during the flight process of the drone and the moment of blasting, all parts of the device can remain tightly connected and no fire extinguishing substance will occur. Loosening or separation phenomenon, a blasting component 4 is arranged in the filling cavity 13 and filled with fire extinguishing material, which can ensure that sufficient impact force can be generated at the time of startup to make the fixed shell 1 rupture quickly, and at the same time, the fire extinguishing material is evenly and fully diffused around the fire source. A plurality of grooves 14 are arranged in a ring shape on the surface of the shell 11, which can guide the rupture direction when the fixed shell 1 is subjected to blasting impact, so that the fixed shell 1 can rupture more quickly and evenly along the distribution of the grooves, thereby improving the release efficiency of the fire extinguishing material. At the same time, the grooves 14 can act as reinforcing ribs to improve the overall strength of the fixed shell 1, so that it can better withstand the action of external forces during transportation and flight, and can guide the passage of airflow during the descent of the fire extinguishing device to improve the stability of the descent process of the fire extinguishing device, thereby improving the accuracy of the falling position of the fire extinguishing device.

[0028] In some embodiments, the blasting assembly 4 includes a blasting tube 41, an explosive 42, and an ignition head 43. The blasting tube 41 is arranged in the fixed shell 1. A fire extinguishing material is arranged on the periphery of the blasting tube 41 to ensure that the blasting tube 41 is firmly installed in the fixed shell 1 to ensure that it will not be displaced or shaken during transportation and flight. The explosive 42 is filled in the blasting tube 41. The explosive 42 can be a pyrotechnic agent. The composition and proportion of the pyrotechnic agent can be adjusted according to different usage scenarios. The ignition head 43 is inserted into the explosive 42 and is electrically connected to the control component 5. It can be connected through high-temperature resistant and anti-interference wires. The ignition head 43 adopts a highly sensitive electronic ignition device, which can quickly generate high-temperature sparks and ignite the explosive 42 after receiving the electrical signal sent by the control component 5. The control component 5 achieves precise detonation of the explosive 42 by accurately controlling the ignition time and ignition energy of the ignition head 43.

[0029] In some embodiments, the explosive 42 may be liquefied carbon dioxide, which can be used to achieve the blasting effect by utilizing the huge expansion force generated when it is instantly gasified. At the same time, liquefied carbon dioxide has the characteristics of being pollution-free and having high fire extinguishing efficiency, and is particularly suitable for fire scenes with high environmental requirements, such as fires in ancient buildings. During storage and use, special sealing and heat insulation measures are taken to ensure the stability and safety of liquefied carbon dioxide, and the gasification process of liquefied carbon dioxide absorbs heat, which can reduce the impact of high temperature generated by the explosion of the explosive 42 on the fire extinguishing effect.

[0030] In some embodiments, the blasting assembly 4 also includes blasting holes 44, which are evenly spaced on the blasting tube 41 and at the bottom of the explosive 42. When the explosive 42 explodes, the explosion energy is released through the blasting holes 44 and the blasting tube 41, and the fire extinguishing material around the blasting tube 41 is sprayed around the blasting tube 41, thereby increasing the area of ​​the fire source covered by the fire extinguishing agent and improving the fire extinguishing effect.

[0031] In some embodiments, the control component 5 includes a control board 51, a battery 52, a start switch 53, and a latch 54. The control board 51 is fixed in the sealing component 2 and is electrically connected to the blasting component 4. The control board 51 can adopt a highly integrated, low-power chipset, and is firmly fixed inside the sealing component 2 with a miniaturized design. It can be fixed by glue and electrically connected to the blasting component 4 through a flat cable with strong anti-interference ability. A timing module can be provided in the control board 51, which can receive and process signals and send precise control instructions to the blasting component 4 to achieve accurate startup of the blasting component 4. The battery 52 is fixed in the sealing component 2 and is electrically connected to the control board 51. The battery 52 can be a high-capacity, lightweight and stable lithium battery, which is also firmly installed in the sealing component 2 to provide a continuous and stable power source for the control panel 51 and the entire control component 5, ensuring that all components can operate normally during the entire process of the fire extinguishing operation, and the fire extinguishing effect will not be affected by insufficient power. The starting switch 53 is set on the control panel 51, which can control the connection and disconnection of the circuit between the control panel 51 and the battery 52. ​​When the starting switch 53 is closed, the circuit between the control panel 51 and the battery 52 is connected, and the entire control component 5 starts to work; when the starting switch 53 is disconnected, the circuit is cut off, and the control component 5 is in a standby state. The plug 54 passes through the sealing component 2, and one end of the plug 54 is pressed on the starting switch 53. The plug 54 can be fixed on the sealing component 2. The plug-in matching structure of the plug 54 and the sealing component 2 is a prior art and will not be repeated here. Before the fire extinguishing device is ready to be put into use, the plug 54 is in an inserted state, and the starting switch 53 remains disconnected to prevent the device from starting by mistake. When the device needs to be started, the operator only needs to easily pull out the plug 54, and the start switch 53 will quickly operate under the action of the internal mechanical structure to achieve circuit connection and prepare for subsequent blasting operations.

[0032] In some embodiments, the start switch 53 includes a start block 531, a start slot 532, a first connecting piece 533, a second connecting piece 534, a movable piece 535, a reset spring 536, and an extrusion piece 537. The start block 531 can be made of high-strength insulating material and firmly arranged on the control board 51, providing a solid and reliable installation foundation for other components of the start switch 53. The start slot 532 is arranged in the start block 531, and the movable piece 535 can slide smoothly in the start slot 532. The movable piece 535 can be made of conductive metal such as copper, and the first connecting piece 533 can be made of highly conductive The movable sheet 535 is made of metal material and is firmly fixed on the inner wall of one side of the starting slot 532 and can be electrically connected to the control board 51 by welding. The second connecting piece 534 can also be made of high-quality conductive material, fixed on the inner wall of the other side of the starting slot 532, and connected to the battery 52. ​​The reset spring 536 is arranged between the bottom of the movable sheet 535 and the control board 51. The extrusion sheet 537 is arranged at the top of the movable sheet 535 and fits with the bottom of the pin 54. The extrusion sheet 537 can be made of insulating materials such as plastic. The top of the extrusion sheet 537 close to the side of the pin 54 can be an arc to facilitate the downward movement of the extrusion sheet 537 when the pin 54 is inserted.

[0033] When the plug 54 is inserted, the squeezing sheet 537 is subjected to the pressure of the plug 54, pressing the movable sheet 535 downward, so that the first connecting sheet 533 and the second connecting sheet 534 are separated, and the circuit is disconnected; when the plug 54 is pulled out, the squeezing sheet 537 loses pressure, and under the elastic force of the return spring 536, the movable sheet 535 slides upward rapidly, so that the first connecting sheet 533 and the second connecting sheet 534 are connected through the movable sheet 535, the circuit is turned on, and the device is successfully started.

[0034] In some embodiments, the control component 5 also includes a fixed line, a fixed column 55, a deformable conductive sheet 56, and a heat-conducting rod 57. The fixed line can be made of high-temperature resistant and wear-resistant wires. The fixed line is connected between the positive electrode of the battery 52 and the blasting component 4 to provide a stable power supply for the blasting component 4 to ensure that the energy required at the moment of blasting can be transmitted in time and accurately. The fixed column 55 is arranged on the control board 51 and can be electrically connected to the blasting component 4 by welding or wire. One end of the deformable conductive sheet 56 is connected to the negative electrode of the battery 52, and the other end is bent and arranged on one side of the fixed column 55. The electric sheet 56 can be made of special thermosensitive materials, such as shape memory alloy. When the external temperature changes, its shape will change accordingly, so that it will deform and connect to the fixing column 55 when heated. The top of the heat-conducting rod 57 is connected to the deformable conductive sheet 56, and the bottom extends to the outside of the fixed shell 1 and is directly exposed to the external environment. When the fire extinguishing device falls from the drone to the fire source, friction generates heat under the action of air resistance, and the temperature of the heat-conducting rod 57 rises by about 1°. The increased temperature will not affect the deformable conductive sheet 56, thereby avoiding misoperation of the deformable conductive sheet 56.

[0035] When the heat-conducting rod 57 senses high temperature outside, such as when it is close to a fire source, it will quickly transfer heat to the deformable conductive sheet 56. The deformable conductive sheet 56 deforms after being heated and connects to the fixed column 55, so that the circuit between the blasting assembly 4 and the battery 52 is connected, and the blasting assembly 4 works to achieve automatic blasting, thereby increasing the intelligence and adaptability of the fire extinguishing device, so that it can automatically respond according to the actual situation in complex and changeable fire scenes, and extinguish the fire in a timely and effective manner.

[0036] The specific working principle is as follows: When in use, first, the drone mounting frame is tightly connected to the mounting plate 32 through the mounting hole 33 using hooks, latches and other connectors, the fire extinguishing device is mounted on the drone, and at the same time, the end of the latch 54 is tied to the drone through a connecting rope to achieve the installation of the fire extinguishing device on the drone.

[0037] The drone carrying the fire extinguishing device flies to a suitable position above the fire source. During this process, the control component 5 is in an unactivated state, the latch 54 is pressed onto the start switch 53, and the circuit between the control board 51 and the battery 52 is disconnected.

[0038] The drone releases the fire extinguishing device, which falls freely under its own gravity. At this time, the pin 54 that penetrates the sealing component 2 and is pressed on the starting switch 53 is pulled out, and the pin 54 leaves the extrusion sheet 537. The movable sheet 535 slides under the action of the return spring 536, so that the first connecting sheet 533 and the second connecting sheet 534 are connected through the movable sheet 535, the control board 51 is energized, and the control component 5 starts to work.

[0039] After receiving the signal (which can be the timer reaching the set time point), the control board 51 sends a signal to the ignition head 43. After receiving the signal, the ignition head 43 quickly generates a high-temperature spark to ignite the explosive 42 in the blasting tube 41. The blasting tube 41 is filled with fire extinguishing material, and the explosion energy is released through the blasting hole 44 and the blasting tube 41, so that the fixed shell 1 is quickly broken under the impact of the explosion energy, and the fire extinguishing material is quickly and timely sprayed to the surroundings to evenly cover the fire source and achieve fire extinguishing.

[0040] When the ignition head 43 does not receive a signal, and the heat-conducting rod 57 senses the external high temperature, such as when it is close to a fire source, the heat-conducting rod 57 will quickly transfer the heat to the deformable conductive sheet 56. The deformable conductive sheet 56 is deformed by the heat and connected to the fixing column 55, so that the circuit between the battery 52 and the blasting assembly 4 is turned on, and the ignition head 43 ignites the explosive 42 to achieve automatic blasting fire extinguishing, thereby increasing the intelligence and adaptability of the fire extinguishing device, enabling it to automatically respond according to actual conditions in complex and changeable fire scenes, extinguish the fire in a timely and effective manner, and reduce the influence of the flight altitude of the drone on the fire extinguishing device.

Although the present invention has been described in detail with reference to the aforementioned embodiments, those skilled in the art should understand that the technical solutions described in the aforementioned embodiments may still be modified, or some of the technical features may be replaced by equivalents.
